The Yarnell Hill fire, that remains uncontained, is located some 85 miles northwest of Phoenix. Earlier on Sunday forestry officials evacuated residents in Yarnell and nearby Peeples Valley with more than 2,000 acres burning. Half of the homes in Yarnell are expected to be lost to this aggressive fire.

The bodies of the 19 firefighters were found in fire shelters while another 22 firefighters were injured. Fire shelters are tent-like structures deployed when a fire moves to quickly around the firefighters.

The Yarnell fire started Friday evening and has been enhanced by strong winds and little rain. The fire is believed to be moving at a rate of about half-a-mile-per-hour with more than 200 firefighters working to contain the fire.
